Twenty-four-year-old Jeffrey Hahn, of Allison Park, faces four to eight years in prison after Tuesday's plea, but the Observer-Reporter of Washington, Pa. (http://bit.ly/WoR0l0 ) reports that can't be imposed until a state board decides whether to classify him as a sexually violent predator. That will take about 90 days.

Hahn was a seventh grade teacher at the Bethlehem-Center School District but allegedly committed the crimes in May at the Charleroi Area Junior-Senior High School auditorium, where he was directing the musical.

Hahn had passed all background checks before he was hired.

He met the girl in March and texted her repeatedly before they finally had sex May 4.
